● Seasonal Growth and Behaviour


'Sardanna' retains its foliage year-round indoors but grows most vigorously in spring and summer. As a rhizomatous Begonia, it produces new leaves from creeping stems, creating a dense and decorative mound over time.

Brown edges: Caused by low humidity or inconsistent watering
Leaf spotting: Avoid overhead watering to reduce fungal risk

● Additional Notes


While Begonia 'Sardanna' can produce flowers, the primary attraction is its ornamental foliage. Display it in decorative pots or groupings with contrasting foliage for maximum impact.
 
● Etymology of Begonia


The genus Begonia was established in the mid-18th century by Charles Plumier, who named it after Michel Bégon (1638 – 1710), a French administrator and amateur botanist who supported plant exploration. 'Sardanna' continues this lineage with a modern, highly decorative foliage form.
